Charles1dad and others, Thank you very much for your comments and excellent advice. Based on my research, I am not going to run my DAC direct into my integrated amplifier. I have been told that most DAC’s do not supply as much drive as a properly designed preamplifier. I seriously doubt that the DACs volume control will match or exceed the quality in my existing Luxman L-590AX.
In addition, I also checked the Luxman 590ax manual and discovered that RCA plugs are required to separate the pre-amp from the Luxman 590ax amplifier (plus the switch on the front panel). This means I CANNOT use my balanced cables from the DAC to the integrated amplifier. It makes no sense for me to have a fully balanced DAC running into a fully balanced amplifier and NOT take advantage of the two balanced units.
Thanks again for all your advice.
